Abstract
A process for producing a zinc oxide acicular structure by growing an acicular zinc oxide on a substrate, the process comprising the steps of holding the substrate in an electrolytic solution in which at least zinc ions are present, and forming zinc oxide on the substrate by electrodeposition. The electrolytic solution contains at least one cosolute. Also disclosed is a photoelectric conversion device comprising a charge transport layer having the zinc oxide acicular structure.
Claims9
A process for producing a zinc oxide acicular structure comprising the steps of:
- holding a substrate in en electrolytic solution;
- and
